The emergence of COVID-19 virus has shaken almost every aspect of human life including but not limited to social, financial, and economic changes. One of the most significant impacts was obviously healthcare. Now though the pandemic has been over, its aftereffects are still there. Among them, a prominent one is people lifestyle. Work from home, enhanced screen time, limited mobility and walking habits, junk food, lack of sleep etc. are several factors that have still been affecting human health. Consequently, diseases like diabetes, high blood pressure, anxiety etc. have been emerging at a speed never witnessed before and it mainly includes the people at young age. The situation demands an early prediction, detection, and warning system to alert the people at risk. AI and Machine learning has been investigated tremendously for solving the problems in almost every aspect of human life, especially healthcare and results are promising. This study focuses on reviewing the machine learning based approaches conducted in detection and prediction of diabetes especially during and post pandemic era. That will help find a research gap and significance of the study especially for the researchers and scholars in the same field.

전기자동차는 화석연료 사용으로 인한 대기오염을 줄여 삶의 질을 개선하고, 신규 사업을 창조하여 경제적 발전에 역할을 할 것으로 기대된다. 그러나 이러한 기대와는 달리 전기자동차의 보급은 쉽지 않다. 주요한 이유 가운데 하나는 화석연료를 사용하는 자동차에 비해 충전이 늦거나 불편하다는 것이다. 전기자동차가 보급되지 않은 상황에서 선제적으로 충전소를 확보하는 일은 비용부담과 관리의 어려움을 야기할 수 있어 주의해야 한다. 본 연구는 디자인 과학 연구법을 활용하고 전기자동차 충전소 결정 문제를 정보시스템 관점에서 해석한다. 주행 범위 불안감을 이론적 근거로 삼아 여정 설계 알고리즘을 제안하고 네비게이션 사용자 데이터를 분석함으로써 서울시 충전소의 위치 선정의 문제점을 확인한다. 또한 여정 설계 디자인의 적용 가능성을 검토하고 시사점을 도출한다.

Purpose: The purpose of this study is to develop a model for predicting mental health risk among adolescents based on health behavior information by employing a hybrid machine learning method. Methods: The study analyzed data of 51,850 domestic middle and high school students from 2022 Youth Health Behavior Survey conducted by the Korea Disease Control and Prevention Agency. Firstly, mental health risk levels (stress perception, suicidal thoughts, suicide attempts, suicide plans, experiences of sadness and despair, loneliness, and generalized anxiety disorder) were classified using the k-mean unsupervised learning technique. Secondly, demographic factors (family economic status, gender, age), academic performance, physical health (body mass index, moderate-intensity exercise, subjective health perception, oral health perception), daily life habits (sleep time, wake-up time, smartphone use time, difficulty recovering from fatigue), eating habits (consumption of high-caffeine drinks, sweet drinks, late-night snacks), violence victimization, and deviance (drinking, smoking experience) data were input to develop a random forest model predicting mental health risk, using logistic and XGBoosting. The model and its prediction performance were compared. Results: First, the subjects were classified into two mental health groups using k-mean unsupervised learning, with the high mental health risk group constituting 26.45% of the total sample (13,712 adolescents). This mental health risk group included most of the adolescents who had made suicide plans (95.1%) or attempted suicide (96.7%). Second, the predictive performance of the random forest model for classifying mental health risk groups significantly outperformed that of the reference model (AUC=.94). Predictors of high importance were 'difficulty recovering from daytime fatigue' and 'subjective health perception'. Conclusion: Based on an understanding of adolescent health behavior information, it is possible to predict the mental health risk levels of adolescents and make interventions in advance.

본고는 식품위험이 현실화되지 않은 상황에서 건강위해에 대한 심리적 불안과 우려로 인하여 발생할 수 있는 소비감소와 후생손실을 2008년 4월 미국산 쇠고기 수입재개 발표에 따른 BSE 위험을 사례로 분석하였다. 조건부가치측정법이나 실험시장접근법을 사용하여 식품안전에 대한 소비자들의 단위당 지불의사나 가격프리미엄을 도출했던 기존의 연구들과는 달리, 소비자들이 기록한 쇠고기 구입량, BSE 위험에 대한 주관적 심각성, 표본내 개인들이 직면한 가격지수 등을 산정하여 개인별 쇠고기 수요함수를 추정하고 소비자들이 주관적으로 체험하는 정확한 후생효과인 동등변화(EV)와 소비자잉여의 변화를 측정함으로써 소비자들이 식품안전성에 부여하는 가치를 측정하였다. 2008년 10월 말부터 11월 중순까지 쇠고기를 소비하는 360명의 주부들을 대상으로 실시한 설문조사 자료를 사용하여 쇠고기 수요함수를 추정한 결과, 수입재개 발표 전 후의 경우 모두 자체 가격, 대체재의 가격, 그리고 소득변수 등의 부호가 경제이론에 부합되었고 통계적으로 유의하였으며 발표 전 후 두 기간 동안에 큰 차이가 관찰되지 않았다. 반면에 수업재개 발표 이후 형성된 BSE 위험에 대한 심각성을 나타내는 변수는 발표 이후의 수요함수에서는 통계적으로 유의한 부의 부호를 가진 반면에, 발표 이전의 수요함수에서는 통계적으로 유의하지 않았다. 그리하여 수입재개 발표 후의 BSE 위험에 대한 우려증가로 인한 품질저하 인식에 따른 소비자들의 후생손실을 측정한 결과 가구당 30,000원 정도로 계산되었다. 또한 이 정도의 후생손실을 가져올 BSE 위험에 대한 우려수준은 수입재개 전에 비하여 35% 이상 증가한 것으로 나타났다.

디지털 창의 노동이란 문화화와 소비주의가 확장하며 노동질서의 유연성과 불안정성이 격화하고 신자유주의적인 이념이 지배적인 자본주의 사회에서, 자유 자율 자발을 추구하는 에토스와 문화적 창의성과 참여를 지향하는 실천들이 디지털 네트워크를 매개로 왕성하게 촉발, 발현, 교통되고, 이들이 정치 경제 문화 권력과 다양한 방식들로 접합 혹은 분절하는 노동 문화를 의미한다. 디지털 창의노동은 개인의 자유를 기치로 표방하는 신자유주의적인 이념 체제 안에 있으면서도 기업화된 디지털 자본주의의 자장 안에서 생성되기에 통치권력과 주체형성의 모순과 갈등으로부터 결코 자유로울 수 없다. 창의성과 열정, 자기 혁신과 성공적인 미래와 같은 긍정적 가치가 강조되는 동시에 이것을 실행하는 경제적 합리성과 자기 경영의 원리가 중시된다. 그 과정에 주체의 의지, 기업의 경영기술, 대중의 익명화된 권력, 사회적으로 팽배한 상상과 환영의 힘들이 개입하면서 자기 통치적인 주체가 형성된다. 이처럼 디지털 창의노동자는 창의성과 자유의 문화적 가치를 지향하고 디지털 네트워크의 참여성과 자발성의 가치를 추구하기에 오히려 신자유주의적인 경제 체제에 타협적으로 접합되는 역설 안에 있다.

This study was done to analyze the trends of research on coping in Korea, to suggest future direction, for research on coping, and ultimately to contribute to an increase in explanation of adaptation. This article reviewed 79 nursing research papers on coping done since 1978 by examining them according to the period of publication or presentation, research design, type of subjects, measurement instruments, research for a degree or not, range of reliability, and association of coping and related variables. The results are as follows : The number of studies on coping increased rapidly from the mid-1980's and decreased slowly from the mid-1990's. The maority of the studies were surveys, comparative studies, or correlational studies. The subects of the 46 studies were healthy people, while those in the remaining studies were patients with a variety of illnesses. Thirth-eight studies on coping were done for master's thesis, three for dissertion, and 38 were not degrees. The Bell and Jalowiec coping scales have not been used since the early 1990's. In contrast, Lazarus and Folkman's W.C.C.L. has been used increasingly since that time. The reliabilities of the coping scale were reported in 37 cases and the Cronbach's alpha coefficients were .71 to .86. All subjects reported using more problem-oriented coping than emotion-oriented coping in short-term or emotion-oriented coping and healthy groups did more long-term coping. It was difficult to describe consistently the relationship between stress and coping according to the type of coping scale or research subjects, but generally moderate relationships were found. This was due to instrumental problems and no consideration of situational context. The subject group who used more short-term coping and less long-term coping reported poorer mental status, and higher scores in burnout and state anxiey than others. That is, the relationship between stress and adaptation increased the power of explanation with intervening the mediating effect of coping. The association of locus of control, mastery, social support, and self-concept with coping showed positive relationships : those of uncertainty and severity in illness with coping showed negativerelationships ; those of state anxiety and depression with short-term coping were positive, and those of self-esteem with long-term coping or problem-oriented coping were negative. There were significant differences in the scores of types of coping according to religion, level of education, and socio-economic status. That is, Presbyterians and Catholics, those with higher education levels and higher socio-economic status used more long-term or problem-oriented coping. On the basis of the above findings the following recommendations are made : 1. There is a need to test the mediating effect of coping variable in order to clarify the concept. 2. Longitudinal studies are needed to determine the patterns of change in coping strategies when stressful events are encountered. 3. It's necessary to develop a reliable and variable measurement tool for coping. 4. There is a need to identify subscales of coping to increase explanation of variance 5. It's necessary to consider personal, situational, and antecedent variables : the characteristics of subject populations, the natures of illness and treatment situations. 6. The power of explanation of studies designed to identify the stress-adaptation process should be increased using the combination model of process-oriented coping and cognitive-structural model.

The purpose of this study is to explore whether the phenomenon of both married and unmarried adults' cohabiting with their parents in Korean society is "unilaterally parasitic" on the child's side, or is "interdependent", characterized by expectation and dependence from the parent's side. As a result of this study possessing the characteristics of theoretic research, the following propensities of parent-dependent adults have been discussed. First of all, it was discovered that the ratio of adult children dependent on and cohabiting with their parents is considerable. Second, parents cohabiting with their adult children have unfavorable sociological features, such as high age, low level of education and income, and lower standards of education and income, compared to parents in normal households. Third, it was found that parent-dependent adults in Korean society maintain a relatively high rate of financial activity and stable employment-based occupation status. Fourth, it was shown that the level of satisfaction on the relationship between parent-dependent adults and their parents was discovered to be high, which is contrastive to the prediction of negative results based on some previous researches. Single adult children's age, their level of education and financial activity status, and their parents' age and level of education were deducted as variables related to the level of satisfaction of the relationship between parents and their children. It seems that the issue of married and unmarried adults' cohabiting with their parents in Korean society should be approached from various perspectives such as political, economic, socio-cultural and developmental aspects. On the basis of this fundamental awareness and several of the materials, it is pertinent that approaches to both married and unmarried adults' cohabiting with parents in Korean society should be distinguished from approaches to those in Japanese or Western society because it reflects the uniqueness of Korean society. In the phenomenon of married and unmarried adults' cohabiting with their parents in Korean society, there are several factors besides the economic factor, especially the socio-cultural factor that have the characteristics of mutual dependence between parents and their children rather than those of unilateral parasitism, in contrast with the phenomenon in Japanese or Western society. This research was aimed to contribute by establishing basic data for policy making by providing necessary information to treat the issues of instability and anxiety related to families and reflection on the matters of generations and parent-child relationships in current Korean society.

Presently there is an increasing demand for home health care services due to changes in the demographic structure as a result of an increasing elderly population, socio-economic improvements, and changes in the family structure, as well as the growing number of people with degenerative diseases. In addition to these reasons, rising medical costs and there a shortage of patient beds space in the hospital, particularly since introduction of national medical insurance. There has been an increasing demand for health care health care services. This study was done to identify the basic data for home health care management. It focused on developing client selection criteria, assessment tools, and recording methods. This was accomplished by the researchers visiting the patients in their homes. The research process included preparation investigation, tool development, training of the project researcher, and visiting the clients in their homes. The research tools are as follows : 1. Record development : a) The selection criteria tool for home health care of postpartum women was a structured tool and consisted of four parts. b) The structured assessment tool consisted of a general items, obstetric history, past medical history, methods of feeding, medications taken before admission, laboratory test results, discharge instructions, discharge medications, family tree, economic status, environmental status, a map, health assessment of postpartum women and their newborns. c) The visit note I consisted of the frequency of visits. Visit note II consisted of the date ; nursing problems ; nursing process including the initial assessment ; nursing goal ; visit plan ; postpartum women and their neonate health status, diagnosis, goal, implementation, evaluation, summary, next plan, for visit revision. d) Problem note consisted of the date, problem numbers, nursing diagnosis, problem appearance date problem resolution date. The research results are as follows : 1. Nursing problems : The nursing problems of the postpartum women and their neonates were evaluated by the number of nursing diagnoses and the change in the pattern of nursing diagnosis related to the number of visits. a) Nursing diagnosis The nursing diagnosis was classified according to physical function, psychosocial function, family system maintained function. b) The changes of nursing diagnosis related to the number of visits. As the type of nursing diagnosis changed related to the number of visits the number of nursing diagnoses decreased. 2. Contents of home health care : The content was categorized according to assessment, direct care, counseling, education, family care, reporting to with the attending doctor. The recommendations based on the research results are as follows : 1. Tool development Replication of this study is needed to test the validity of the assessment tools used. 2. Home visit a) Home health care nurses should be licensed and qualified. A referral form from the attending doctor is needed for legal protection of nurses. b) The first home visit need to be within 24 hours of discharge from the hospital to decrease the anxiety of frightened postpartum women. c) When the changes occur in the newborn's status, home health care nurses should consult a pediatrician. Communication within the home healthcare team is essential and needs to consistent and done smoothly. 3. Home health care A Study is required to develop protocols for education of staff and for operation of all aspects of this program.
